I am a self-taught Astrologer. I have worked with other Astrologers, but primarily I have learned my craft through personal experience, lots of hard practice, and books! So, here are the important books you will need to begin the process of becoming not just a good Astrology caster, but a great one!
Start off with Linda Goodman's Sun Signs, then you will need to read Love Signs, that is for some reason the most well written Astrology bible that will get you familiar with the way all the signs, planets, and houses relate to each other. Its complicated to explain, but definitely trust me on this. It gets you seasoned!
My relationship signs book is so tattered its not even funny. It has all the planetary tables in it so you can find out easily where all your planets reside and in which houses respectively and that it explains a lot about how people relate to each other in conjunction with those houses and signs. Its so helpful in the learning of Astrology, you will see!
Parker's is a little more detailed and gets into how the individual sun signs are divided up and what your power stone for your exact birthday is and what you should be eating and watching health wise and such. Its a really well written book!
The Astrology Handbook gets very super detailed and tells you how to cast lots, something done in Vedic Astrology to predict life's events and the circumstances surrounding them such as the birth of a child, profession, marriage, divorce, addiction, mental illness, things of that nature...
Oh, I think somebody is partial to Linda Goodman lol, have you deduced that yet? Buy 'em used and resell them when you are done or pass them on! I put a couple of books that I suggest you buy used off of Amazon up. Its super cheap and super easy and comes quick!
Enjoy and I hope you check these special books out and begin learning my craft. I am always here to share and to do your chart, so don't hesitate to email me with any questions, customastrocharts@gmail.com!
